Light & Matter
how does light travel
in straight lines
what are heat conductors
silver, copper, gold, and aluminum
what is wind
wind is moving air
what are plate tectonics
The theory that the earth is broken into plates and are in motion due to convection currents in the asthenosphere (upper mantle)
what are the three types of muscle tissue
skeletal, cardiac, and smooth
does not allow light through
opaque
what is thermal energy
thermal energy is the sum of kinetic energy and potential energy in the particles that make up a material
what is humidity
The amount of water vapor in the air
who Proposed the continental drift theory in the 1900s
Alfred Wegener
what does the muscular system do
causes movement when muscles contract(shorten)
what does not block light
transparent
this is the measure of the average kinetic energy of the particles in a substance
temperature
what is Evaporation
The change of a substance from a liquid to a gas
what is The thin and solid outermost layer of the Earth above the mantle
the crust
what does the skeletal system do
supports an organism's body, protects its internal structures, and allows the body to move
what does light bounce off of
reflection
what is radiation
Radiation is energy that travels from a source in the form of high-speed particles or electromagnetic waves
The condition of Earth's atmosphere at a particular time and place.
weather
what is the Lithosphere
The solid, outer layer of the Earth that consists of the the crust and the rigid upper part of the mantle
what are the respiratory system organs
lungs, airways (trachea, bronchi, bronchioles), diaphragm, pharynx, larynx, and nose
what is a group of color seen when white light passes through
spectrum
what is conduction
Conduction is the transfer of heat or electricity directly through a substance or between materials in contact, caused by molecular collisions
what is the instrument used to measure wind speed
anemometer
what is the Asthenosphere
The soft layer of the mantle on which the tectonic plates move
where did the word trachea come from
The word trachea originates from the Greek phrase trakheia artēria, meaning "rough artery" or "rough windpipe"
